Kindergartners from DaVinci Academy released rainbow trout theyâd raised from eggs into the Ogden River on Friday, under supervision from Utahâs Division of Wildlife Resources and conservation group Trout Unlimited. The class started out with 200 eggs, donated along with food by DWR and Trout Unlimited, and teacher Eleanor Sather received a $1,500 grant from the STEM Action Center to buy a 55-gallon tank and other supplies.
